I mean , you know , it , there's , there's , there's such variability between muscle groups and you're , you're linking them all together . Um I , I think that coming back and using muscle soreness as a guideline for that is , is one of the only tools we have in terms of the local level , you know , we don't really have , you know , being able to measure let's say , uh CPK levels inside of a muscle would be amazing , you know , at , at a local level to see how , how recovered that muscle is . But that becomes fairly invasive .
I mean , I , I think that at the basic level , that's the one that most people can relate to and easily identify and then use that as a guideline . And if you're training when you're really sore , um it's probably not a great idea and then it's probably a good indication that that muscle is not recovered , but at least hearing what you and I are saying here might be a comfort to the person to say , yeah , it is possible that it's not recovered just because 48 hours is the recommendation and just because research points to muscle protein synthesis , needing a restimulation , well , maybe not , maybe you're not necessarily there yet . You're in that and for that muscle you're not there yet .
Meaning at the level of the muscles ? So we'll talk about soreness and getting better , stronger , more repetitions , et cetera . And then the systemic level , the level of the nervous system .
If the goal is to challenge muscles and one is dividing their body into , let's say , you know , a three or four day a week split or so , or maybe up to six . how do you know when a muscle is really ready to be challenged ? Again ?
But like , you know , in that , that can vary from person to person for sure . And it can vary from muscle to muscle in that person over the course of time . A as you mentioned , because the systemic recovery is gonna impact all those muscles anyway .
